To a/ZZ whom it may concern:

Be it known that I, CHARLES T. DANIEL, a citizen of the United States ofAmerica, residing at Owensboro, in the county of Daviess and State ofKentucky, have invented new and useful Improvements inInjecting-Needles, of which the following is a specification.

This invention relates to improvements in injecting-needles, andparticularly to a needle of this character designed especially forinjecting a preservative salt solution into meats to prevent decay orsouring of the same along the bones or at the joints where decay usuallybegins.

The object of the invention is to provide a needle which is soconstructed as to prevent stoppage ofthe outlet or outlets by the meatwhen the needle is introduced therein, thereby insuring the freeinjection of the preservative fluid, and which is also provided withmeans to retain the fluid in the meat and prevent it from escaping andflowing back along the outside of the needle.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, in which- Figure l is a side elevation oftheimproved needle, and Fig. 2 is a longitudinal section of the same.

Referring now more particularly to the drawings, the numeral 1represents the barrel ofthe needle, which is provided with alongitudinal bore or passage 2, opening through the rear end of thebarrel, the barrel being provided at said end with a ribbed or threadedenlargement 3 to adapt it for attachment to any ordinary syringe. Thebore or passage 2 is closed at the front end of the barrel by anintegral portion 4, which is shaped to form an introducing-point. Adjacent to the point ithe barrel is provided with one or more lateral orside outlet-passages 5,

' through which the preservative fluid discharges from the passage 2into the meat to be preserved. By forming the discharge outlet oroutlets in the side of the barrel the closure or stoppage of said outletor outlets by the meat when the needle is introduced therein isprevented, thus overcoming the known objection to needles of that kindin which the outlet extends throu h the point end, so that a freedischarge of t e preservative solution and its perfect distribution isinsured. Immediately in rear of the outlet or outlets 5 thev barrel isprovided with an annular boss or enlargement 6, preferably havingtapered or beveled front and rear ends 7 and 8. This enlargement may beintegral with the needle, or it may be formed of a hub or sleevesuitably secured thereon.l It serves to form a convenient grip orhandpiece by which the instrument may be conveniently inserted andwithdrawn, and also as a stopper or closure for the opening or passagein the meat formed by the point and outlet end of the barrel, thebeveled Vportion 7 closing such passage and preventing the introducedfluid from escaping and iiowing back upon the outside of the needle, sothat all of the fluid injected will be retained for preservativepurposes.

By the use of this invention a salt solution or preservative fluid maybe readily, quickly, and conveniently injected into a portion of meatalong the bone or at the joint to prevent souring or decay at thesepoints, where it ordinarily begins, and the construction of theinstrument is such as to secure the free introduction of the fluid andthe retention of the whole, or a greater portion thereof, in the meat tobe preserved.

Having thus described the invention, what I claim is- A needle forinjecting a preservative salt solution into meats, the same comprising abarrel having an introducing-point closing the outer end of the borethereof, said barrel being provided adjacent to said point with one ormore lateral outlets, and an enlargement upon the barrel immediatelyadjoining said outlets, said enlargement having a beveled end located inclose contiguity to the rear ends of the outlets to enter the opening orpassage in the meat formed by the point and outlet end of the barrel,whereby said enlargement is adapted to serve the oombined function of afinger-grip and a stopper to close the opening in the meat to preventthe escape of the injected solution, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES T. DANIEL.
